Sinusoid rotary position encoders - RPE3-8 and RPE3-635. 4-20mA output
Sinusoid releases 2 new rotary encoders - RPE3-8 and RPE3-635. Both have 4-20mA current output and a wide voltage supply range of 12-28V.New range of rotary encoders available from Sinusoid
Sinusoid Pty Ltd has just released new range of its rotary encoders. They offer 10 bit resolution and come in several output formats. These are based on contactless magnetic encoder chips from Austriamicrosystems.
Manufactured in rugged anodised aluminium and built with dual ball bearings they offer high speed continuous rotation up to 7500rpm.
There is a v-ring seal which provides IP50 ingress protection for speeds up to 3000rpm.
New Audio Kit demonstration video
Dailyappshow have just shot a video demonstrating the features of Sinusoid’s Audio Kit app for iOS devices.
See it on the Dailyappshow website or on Youtube.
Audio Kit is now at release version 1.5
The App includes the following tools:
- A real time Spectrum Analyser
- Scope – an oscilloscope to display waveforms
- an SPL (sound pressure level) Meter
- and a sine wave Signal Generator
Sinusoid rotary position encoders - RPE1, RPE2
Update: New all aluminium encoders have been release in July 2012.
See the Sinusoid site for details.

Printed Circuit Board production for prototypes - Toner transfer method
Printed circuit boards using toner transfer method.
While there are many sites on the web describing the toner transfer method of circuit board manufacture, none of them worked exactly as I wanted. The following is the method I have perfected to suit my needs for one off prototyping. (PCB toner transfer method)
eZ430-F2013 Development tool
This looks like a unique development tool by Texas. Containing a development platform for an MSP430F2013 on what looks like a USB memory stick.
It is self contained, deriving its power from the USB bus, and has a removable target device board.
TI are offering it for $20 USD including software.
